Perry claims that she was seated in close proximity to the stage in the disabled section when Brown began to reach out to shake hands with audience members. According to the suit, this caused a crowd of people to flood the disabled section, pushing her against a metal gate between the section and the stage. When a security person lifted a metal gate in the section while attempting to control the crowd, the suit claims, the gate caught Perry under her armpit.

According to the suit, Perry suffered neurological, muscular and orthopedic injuries — the complaint says that, as a result, she “does not have the physical ability to use her arm to hold her white cane, thereby limiting her ability to navigate while walking.”

Representatives for Brown and Live Nation Entertainment, also named in the suit, have not yet responded to TheWrap’s request for comment.
